Well, it seems to be working great now! Unfortunately, I loaded the wrong endmill, so the finish is terrible, but it worked!

Well, that was the issue - my brake was enabled the whole time when I was trying to tune it. Sigh.



I'll post another video once I have the belt back on and have it turned and cutting. Thank you all for the help!!

ALSO When playing with CTRL ALT f to cycle the output MAKE SURE YOU DON'T LEAVE IT OFF. There should be NO line under the LED. You left it OFF in your video. When you do that, it will not function. Press CTRL ALT f until there is NO line under the LED. That is the NORMAL state. AH!! I'll bet THIS i...

Here's a quick video of the z-axis running great, and the contactor firing manually...

Here's the latest report file. I'm uploading a quick youtube video of the machine from this morning... you'll see it's working correctly with the z-brake jumpered, but you'll also see that the contactor is working properly. Not sure what that means... maybe the control isn't configured for the z-bra...

So, I will have a report later today - I did a little messing around the past couple of evenings with a friend, and found that we might have a contactor issue on the z-brake - or the params for the z-brake are set incorrectly, so it's not releasing at the right time. Bypassing the contactor with 90v...

Does the Z axis have its own pair of wires for the Z axis brake? If so, you should be using Output 9 to control the Z axis brake. You need to know the voltage of the brake. Usually +24VDC, and usually fed with its own power supply. This way the brake is applied with power OFF, the control will clos...

Im sure its a weight issue on that head compared to the X/Y axis or the head moving down with gravity. Thanks for chiming in! If you review the previous posts and videos you'll see that the problem remains even with the motor disconnected from the z-axis head. It appears to be either a control issu...

So, I learned a few things - first, the 90v to the Z-brake is applied as soon as the e-stop is released. This is fortuitous, since I forgot to jumper it. :) Next, the z-axis is SIGNIFICANTLY smoother after switching the z-axis motor and encoder cables to the x-axis ports on the AIODC board. That bei...

So, if I understand correctly, you were still running the Z axis motor using the Z axis output from the servo drive; it was only the intervening power and encoder cables, plus the encoder itself, that you swapped from the X axis. Is that correct? Yes, exactly. I swapped the motor power cables a cou...
